Application led February 26, 1909. Serial No. 480,126.

To all whom it may concern:

Be it known that we, EDGAR S. STEM and THOMAS S. BOYD, citizens of theUnited States, residing at Alderson, county .of Luzerne, State ofPennsylvania, have invented a new and useful Music-Holder, of which thefollowing is a specification.

This invention relates to collapsible and portable devices for holdingbooks or sheets of music, of the type shown in U. S. Patents 823707 and823708 granted l une 19, 1906.

One of the Objects of the present invention is to provide an improvedholder for the backs of the leaves of sheet music, which holder servesas a standard or upright from the base.

Another object of the invention is to provide improved means on the basefor holding a book of music open.

Another object of the invention is to provide an adjustable base platewhich may be madeV to fit the music support or shelf of any piano.

With these and other objects in viewr the invention consists in certainconstructions and in certain parts, improvements, and combinations,which willbe hereinafter described and then specifically pointed out inthe claims hereunto appended.

vOf the accompanying drawings :Figure the novel `leaves may rest.Mounted in suitable bearings-on thebase is a rock shaft 17 having ahandle 18 and having arms 19 secured to it, a suitable spring 20v beingemployed to actuate the rock shaft so that the arms 19 will bear againstthe lower faces of the music .and hold the leaves open. It is to beunderstood however that the arms 19 will be arranged to press againstand hold open either the backs of the books or sheet music, or allleaves excepting those which are to fingers hereinafter described.

When flexibly connected leaves of music are used in the form which iscommonly known as sheet music, having n stiff binding, it is essentialthat some means shall be provided for grasping the back edges of thesheet music. The present construction in this respect comprises astandard consisting of a strip of sheet Vmetal 21 of sufficientthickness, said strip having a tongue 22 at its lower end which tongueis slipped through a slot in the top plate of the base as indicated bydotted lines in Fig. 1. The sides of the strip 21 slip between lugs 23which 4are struck up from the material of the upright strip 16. thestandard or strip 21, and its leaf clampn ing members presentlydescribed, to be separated from or connected to the base members by asliding movement. -No screws or other fastening means are necessary,thelips or lugs23 grasping the edges of the strip 21 with sufficientfirmness so nthat, in connection with the tongue 22 entering thebase,they will hold the standard rmly in upright position.

The standard carries vertical clamping rods one yof which, 24, is fixedas by being solderedto the ends of lips 25 struck "up from thematerialof the strip 21. Other portions of the strip 21 are struck up to formbearings for a rock shaft 26 having arms 27 to which a rod 28 issoldered. The upper end of said rod 28 is bent to form a handleor lingerpiece, and suitable springs 30 are employed to rock the shaft 26 in adirection to cause its arms to carry the rod 1 is a front 4elevationillustrating music holder and turner as in operative position on a musicrack or holder, the position of an open book or sheet of music beingindicated by dotted lines. Fig. 2 is a plan view of the same. Fig. 3represents a section on line 3-3 of Fig. 1. Fig. l is a detail frontelevation of a portion of the base. Fig. 5 is an under plan view of theparts shown in Fig. 4c. Fig. 6 is a view looking from the right of Fig.4.

Similar reference characters indicate the same or similar parts in allofthe figures.

The base 15 which may consist of a strip of wood, has an angle platesecured to its top, the upright portion of said angle plate beingindicated at 16, lthe same forming a vertical strip against which thelower portion of the back of a music book or set of be turned by thearms and` This structure enables the covers of the Y By operating the ofleaf turning mechanism which, however,

on, is not h-'erebeing an independent inventi in claimed. The leafturning mechanism is contained Within a casing 21 and may be op- 5erated either by the .as desired.

may be provided of suitable soft material to avoid marring the Woodworklof the music rack '64 of the piano. To firmly hold the entire device inplace on -said music rack, the base provided vvi'th an 'adjustable'st-rip k65 having an upturned ear 66 .at each end to receive a screw'67, said lscrevv passing through a 'slot 68 'in Va lug 69 fixed to theend Aof the base 15. By means 'of this .slot ands'crevv vcon- Ji-notmeans carried b s ne'ction, the strip '65 can be 'a'djusted'according.to the vvidv h of the recessed portion or trough of the music rest ofthe piano or 'other musical instrument. f v

"lo hold the 'arms 19 away from the back strip 16 While a b'o'ok 'orloose 'sheets are being putin pl vided for the handle 18., said`catch'comprising 'a plunger 72 :('see Figs. 1 and 2) which is mountedinthe base 15 and normally projected .by a spring 73 in 'a recess in thebaise behind the plunger. Said `plunger isjat such distance from theaxis of the rock shaft 17 that the handle "18 will snap under it Whenturned to its limit outward and downward, but yso that an inward ressure'of the finger on said plunger Will re'easev the handle.

edo not limit yourselves to the precise details o'f constructionillustrated and ldescribed, as the .same ma `be variously modiiiedWithin the limits o mechanical skill.
